Mathematical Proof on " Essentially the same as"

[Artur]

Dear Seqfans,

In ONEIS occured many sequences with sentence  	
"Essentially the same as A........"

Yesterday I was find mathematical proof on one of them.

I was proof that proposition
A023424 Essentially the same as A074048
is false

A023424 can be represented as traces of successive matrix powers of  
pentanacci matrix
A074048 doesn't exist such matrix m that A074048 can be represented as  
succesive matrix powers of matrix m
