Nins and me got *different* random matrices : his was composed of integers in (-2..2), and Sage could compute its eigenspaces ; mine was : sage: with seed(0): M = matrix(AA, 3, 3, lambda u,v: AA.random_element()) sage: M.apply_map(lambda u:u.radical_expression()) [ -sqrt(2) - 1

My point is that it is the same on Apple Mac, that it isn't related to the recent interface and multiprocessing problems but has just appeared with the 9.5 kernel beta release as it works with the 9.4 kernel. On Sunday, February 6, 2022 at 8:53:51 AM UTC Emmanuel Charpentier wrote: > That was
