Leroy asked:
are 2 sequences that have the same terms as far as the EIS database is 
concerned, but differ at higher index(es),    considered officially to be 
the "same" sequence or different  sequences?

Me:  it depends!
if one is a trivial variation of the other, then
one sequence is enough, with a comment saying something:
"if zeros are excluded then the sequence changes after term 120"

but if they are quite different sequences then they would
get separate entries, with a comment saying they differ
after term 120.  and if 120 is small enough then i bend the
rules and give the first 121 terms to show where they differ
