Cholesky/Pascal identity
Hi, you wrote "an upper triangular matrix is not a symmetric matrix => the Cholesky decomposition or Cholesky factorization is a decomposition of a Hermitian, positive-definite matrix"
And yet I get: cholesky(pascal_upp(i)) == identity(i)

Combinations code for Maxima
Hi Arbautjc, aka Capra H!
Kudos 4 your Maxima code for combinations, it works fine, on maxima, even on moodle (-stack plugin), unless the rest of my code. If I get it 2 work once, I'd probably need a GPL licence like the other moodle stuff. Can you give it an additional licence like GPLv3+ and possibly say so on your Userpage?
I wrote automated math questions btw, like 1/3-1/4=?, it chooses denominators from a combinations-list of (2,3)(2,4)(2,6)(3,..).

Two formulae invisible in the GAP contribution on Machin-like formulas
- I notice that two of the <math> tagged formulae in the preamble to your GAP contribution:
- are invisible on the majority of browsers. Chrome, IE/Edge, Safari and most other browsers all display the server-side graphic for formulae, and something about two of your <math> tag contents/contexts seems to be tripping the MediWiki HTML generator into producing ill-formed display tags for them (zero image height, because, in each case, of a missing semi-colon between two attribute names);
- Perhaps these formulae were originally edited on Firefox, which, (installed fonts permitting) uses local MathML processing rather than displaying the graphic file ?
