University of Waikato

Nick Cavenagh, Entertainment Officer for the 41ACCMCC dinner, looking very suave in shades and a leather jacket, launched into song inspired by the musical {\em Grease}. He was soon joined by Ian Wanless, the spitting image of ONJ! Unfortunately the bemusing performance is not on YouTube, but here are the lyrics.

To the tune 'You're the one that I want'

I've got Lagrange multipliers
And they're giving me control
Of this function I'm analysing
It's maximising!

You better shape up.
Your notation stinks
your lemmas lack transparency,
You better shape up.
You gotta generalise!
You need a thorough lit review. Yes you do.
(Anything more? Anything more that I should do?)

It's the proof that we want, proof we really want. Ooh, ooh ooh.
It's the proof that we want, proof we really want. Ooh, ooh ooh.
It's the proof that we want, proof we really want. Ooh, ooh ooh.
It's concise! So very niiice!!!

If you're researching some conjecture
That's too hard to formulate
Iterate in my direction
Coauthor me today

You better shape up
'Cause I need to optimise
And my function is convex
So you better shape *up*
I think you understand
That your theorem must be true
(QED, nothing else we need to do)

It's the proof that we want, proof we really want. Ooh, ooh ooh.
It's the proof that we want, proof we really want. Ooh, ooh ooh.
It's the proof that we want, proof we really want. Q.E.D.

To the tune 'Greased Lightning'

It's mathematic
It's subquadratic
It's 3-chromatic
Why it's Graph Theory! [Graph Theory!]
Let G be a graph. We'll all have a laugh
4 colours on a map, it really is a snap
7 bridges you must cross; Can't do it -- that's your loss
Go Graph Theory, put the work in networks yeah
(Graph Theory, go Graph Theory)
Go Graph Theory, You just have to join the dots
(Graph Theory, go Graph Theory)
Any ram can see, K6 arrow K3. That's Ramsey

A quantum random walk, let the eigenvalues talk
(Graph Theory, go Graph Theory)
Lopsided LLL -- it's not that hard to spell
(Graph Theory, go Graph Theory)
That weighted spanning tree, seems like Christmas came early
Phylogenetic tree shows how bugs relate to me
Go Graph Theory, putting the work in network yeah
(Graph Theory, go Graph Theory)
Go Graph Theory, You just have to join the dots
(Graph Theory, go Graph Theory)

The website for the Australasian Journal of Combinatorics is

AJC is a 'diamond open access' journal: online and free for readers and authors. There are three volumes per year, closing respectively in February, June and October, matching the time of publication of the old paper volumes. Volumes are currently being uploaded in three parts. All of Volume 73 has now been uploaded, and Part 1 of Volume 74 will appear online shortly.

The contents of all volumes 1 to 73 are listed at the above web page.

Visit to register for email notices whenever new papers are published.

Submissions to the Australasian Journal of Combinatorics may be sent to Only pdf files are required at submission stage.

The Journal is now indexed by Scopus from Volume 13 (1996) onwards, and by Thomson Reuters "Emerging Sources Citation Index" from 2015 on.

ISSN: 2202-3518 (online only, after 2013); 1034-4942 (paper, before 2014).
