force transforms and a seemingly nice sequence

Dear Seqfans, 

Exactly the same iterative process described a few days ago (but applied
to a totally different floretion) seems to lead to at least one nice
sequence.  

Floretion:  + .5'i + 'kk' + .5'jk' , 
Step 1: Transform tesseq by forcing vesseq to take on its values.
Step 2: Step one will have yielded a new sequence- the sequence
"tesforseq". Repeat step one (replacing the words  "tesseq" with
"tesforseq" and "vesseq" with "vesforseq").

***************** 0th iteration *******************

1vesseq: 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 

 
 1tesseq: 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0,
 
 
 2lesseq: 3, 0, 3, 0, 3, 0, 3, 0, 3, 0, 3, 0, 3, 0, 3, 0, 3, 0, 3, 0, 3,

Does anyone have a better name than my "LoopType: tes (2nd iteration)"
given inside the sequence program code? 

Important: if someone is interested in co-authoring some explanations of
force transforms with me (or would just like to help me get some of my
ideas straight) please let me know. Warning- a part of me is very used
to working alone ... so you may have to be overly patient with me as I
have, on top of a lack overall  mathematical knowledge, also developed
all sorts of mental shortcuts along the way. 

Sincerely, 
Creighton
