I'm running OS 10.9.5, and the downloads for sage 7.4 are for OS 10.11.6. On Thursday, November 3, 2016 at 7:40:49 PM UTC+11, slelievre wrote: > > > > Thu 2016-11-03 04:43:57 UTC+1, s meagher: >> >> I'm getting the following message when launching sage in the terminal. >> I tried the SageMath App

[sage-support] Re: Summation bug in Sage? In Maxima?

Probably for the same reason as maxima, the singularity n=1/2 inside the summation domain, if you start at 1 the answer is correct. Now fixed in geogebra svn and in xcas offline http://www-fourier.ujf-grenoble.fr/~parisse/xcasen.html#+normal(sum(1/((n+1)*(2*n-1)),n,0,inf)&

[sage-support] Randomness test

Hi, I have sequence like {57, 44, 40, 57, 50, 53, 17, 24, 20, 3, 8, 51, 62, 56, 2, ..}, where each value is between 0 to 63. I want to check its randomness. Is there any function in Sage for this? -- You received this message because you are subscribed to the Google Groups "sage

Re: [sage-support] How can I double check a non-isomorphism between graphs?

you might try to find a combinatorial invariant distinguishing graphs here, e.g. the 4-vertex condition (introduced in http://www.ams.org/mathscinet-getitem?mr=340088 more references here: http://link.springer.com/article/10.1007/s10801-014-0554-1) On Thursday, November 3, 2016 at 12:13:52 PM U
