Just curious if anyone had thoughts to offer on where the 744 comes from. I know it's the second term in the q expansion of the j-invariant, but since I am not much familiar with the intricacies of the maths for either q or j, I'm kind of flummoxed past that.(adsbygoogle = window.adsbygoogle || []).push({});

TIA for any thoughts,

AC
