以前12用ibug这里的可以激活(根据MathId算出来的),刚才下载了Mathematica 13,用生成的激活码竟失败了.
ibug这里的注册机是完全用Javascript实现的:

Stable release        13.2.0 (December 14, 2022)
Stephen Wolfram-The Latest from Our R&D Pipeline: Version 13.2 of Wolfram Language & Mathematica

Dramatically Faster Polynomial Operations
Factoring this isn’t an easy computation, and in Version 13.1 takes about 19 seconds:

But now, in Version 13.2, the same computation takes 0.3 seconds—nearly 60 times faster:

Version 13.2 also adds a polynomial feature for which I, for one, happen to have been waiting for more than 30 years: multivariate polynomial factoring over finite fields:
