Everything is fine sage: graphs.GrayGraph().diameter() 6 sage: graphs.FosterGraph().diameter() 8 If you define a graph with a variable called Gamma and then call a method of *another* variable G then do not expect to get the answer to a property of Gamma... Vincent On 02/10/15 19:01, David

Simllar problem with the Gray graph: sage: Gamma = graphs.GrayGraph() sage: G.diameter() 8 (it should be 6) G = graphs.LCFGraph(54, [-25,7,-7,13,-13,25], 9) sage: G.diameter() 6 seems to be the Gray graph On Fri, Oct 2, 2015 at 5:47 PM, David Joyner wrote: > On Fri, Oct 2, 2015 at 5:44 PM, Davi

[sage-support] girth of the Foster graph?

Hi all: Several online sources (including a page on Royle's website) give the girth of the Foster graph to be 10, but Sage gives 6: sage: Gamma = graphs.FosterGraph() sage: G.girth() 6 Is there a bug in girth? - David -- You received this message because you are subscribed to the Google Group
