See a pattern to this sequence?

[Creighton Dement]

I placed the sequence  "4ibasesumseq" along with those in context at
http://www.crowdog.de/SeqContext/jumpy.html

The number of terms listed per sequence was upped from 200 to 500 -  I
was just waiting for the sequence to begin repeating itself at some
point (the longest period of a floretion sequence I have ever found
using the symseqs to date is 60)... it doesn't appear to do this yet. 

I suspect there is a pattern with the signs (note there never appear to
be 3 same signs in a row if one agrees that number 0 has no sign).  I
haven't checked for this thoroughly yet. 

Final note: the sequence at the link is listed as ibaseseq - it should
actually be written "ibasesumseq". The symseq "sum" (as it is defined
here) is still very new. I need to update FAMP on my websight to cover
this new symseq. I will let anyone who wishes to know know once FAMP has
been updated.
