comment How to draw line connecting points on circle
@rm-rf The points are put on circle in same distance from each other. Since we have 8 values I think we can use 2pi/8. Then I want to connect 1-1, 2-2,likewise. think correct word is label (not mark).

comment How to remove duplicate characters from a string?
@Michael E2. At beginning I thought if I can delete duplicates without converting them to string I may save some memory and make program fast. But it look like my program getting very slow when I do that. So best way I think convert each string to characters when it is processed. May be I should change the question statement

@Michael E2. I agree. When I tried to delete duplicates without converting them to characters it become very slow.

@Michael E2 Yes I can do that. But suppose we have one string. Which one is fast?Split to character->delete duplicate or delete duplicate without splitting it to character?? Any idea??

@rm -rf In 1995, Dror Bar-Natan compute dimension of vassiliev knot invarients up to 9. math.toronto.edu/~drorbn/papers/OnVassiliev First you build chord diagrams which represent knots. cornellmath.wordpress.com/2007/12/13/chord-diagrams. After that you take out 1T and 4T relations. Dror stop at case 9 because data files really big. In 1997 Jan A. Kneissler computed dimensions upto 12 arxiv.org/abs/q-alg/9706022. They compute rational basis. I want to compute different type basis for my research. So case 10,11,12 are stand for chord diagram of order 10,11,12.
