[sage-support] Error occurs when using print_strings() for twisted type D affine algebras

Hi all, Does anyone have any idea why the following codes don't work? Lambda = RootSystem(['D',3,2]).weight_lattice(extended=true).fundamental_weights() V = IntegrableRepresentation(Lambda[2]) V.print_strings(depth=5) It gives "AssertionError: m: error - failed to compute m(1, 1, 1)". I

Thank you, Matthias. I was indeed able to build sage after passing "--without-system-singular" to "./configure". Still working on figuring out how to merge the branch of the ticket you suggested. Best, Alex On Thursday, January 5, 2023 at 10:54:13 AM UTC-8 Matthias Koeppe wrote: > I see the

[sage-support] Re: Matrix_generic_dense.det() is quite slow compared to Numpy

One way to speed it up might be to work with RDF or QQ or RLF. The documentation for the generic determinant method says, "Note that for matrices over most rings, more sophisticated algorithms can be used." sage: %time ones_matrix(RDF, 600, 600).determinant() CPU times: user 78.6 ms, sys: 7.6

I see the following error in sagelib-*.log: #define LOCAL_HIREMAINDER register ulong hiremainder ^ sage/rings/polynomial/multi_polynomial_libsingular.cpp:35068:120: error: use of undeclared identifier 'pTakeOutComp1'; did you mean 'pTakeOutComp'?
