In the documentation for CubeConnectedCycle, it says

static CubeConnectedCycle(d)

But when I try to run the following example given in the same page above it is giving an error.

d = 3
g = graphs.CubeConnectedCycle(d)

The error shown is

AttributeError: GraphGenerators instance has no attribute 'CubeConnectedCycle'

Can someone tell me what went wrong? Thanks in advance.

I can not reproduce it, on my installation i get:

sage: d = 3                                                                                                                                                                                                  
sage: g = graphs.CubeConnectedCycle(d)                                                                                                                                                                       
sage: g                                                                                                                                                                                                      
Cube-Connected Cycle of dimension 3: Graph on 24 vertices

It seems that this generator was introduced in Sage 9.1, see https://trac.sagemath.org/ticket/21423

Which version are you using ?

I was using 9.0. I installed 9.2 now and is working well. Thanks a lot!
