bands computed: 5742 (rays from O, both sides); largest number of segments of a simple preclosed piece: 46
odd n: in every class exactly m = 17 preclosed lengths c*lambda*sin(2j pi/n)/sin(pi/n), factors d_j = n'/gcd(n',j); classes by n': {35: 34, 7: 6, 5: 4}
  n'=35: factors 35,35,35,35,7,35,5,35,35,7,35,35,35,5,7,35,35  gcd 1  a quotient is n: yes  classes: 34
