On May 10, 2008, I realized that Stewart’s choral sequence (which I talked about in a previous blog entry) is a specific case of a more general set of cube-free sequences, which I called generalized choral sequences.
A few months later I wrote a paper about them which I presented at the 2009 Severino V. Gervacio Conference in Graph Theory and Combinatorics. It was published in Matimyás Matematika in 2009.
On November 2009, I finished writing a longer paper about them. I will be presenting it at the 2011 Mathematical Society of the Philippines annual convention.
