in this page ive encountered this topic (it's a topic from combinatorics, so it's relevant to discrete maths with sets and so on [that's my justification to post it here ), anyway from my point of view the page describes poorly the successor operation:(adsbygoogle = window.adsbygoogle || []).push({});

"The resulting

sequence of elements constitutes another loop, which we will call

the "successor" of the original loop."

here's an example of such successor from the webpage:

I = 123 C = 231

A = 132 D = 312

B = 213 E = 321

IDEACB = A

DEACBI = A

EACBID = B

ACBIDE = A

CBIDEA = A

BIDEAC = E

i dont understand why for example the first sequence of elements equals A (or is identical to it), perhaps i missed something from the explanation, anyone care to explain.

btw, here's the page:
