Cyclic LS

Enumeration:
  • A338522 — Number of cyclic Latin squares of order N
  • A000010 — Number of cyclic Latin squares of order N with fixed first row (Euler totient function) (was known before me, interconnection with cyclic LSs established)
    • Transversals:
  • A006717 — Number of transversals in cyclic Latin squares of order N (N<26) (was known before me, same value for all cyclic LS of order N)
    • Intercalates:
  • A000290 — Number of intercalates in a cyclic Latin squares of order N=2n (value is zero for odd orders, same value for all cyclic LS of order N)
    • OLS:
  • A091261 — Number of orthogonal mates for the cyclic Latin squares of odd order (N<12) (was known before me, same value for all LS of order N)
    • Semicyclic LS

    Enumeration:
  • A343868 — Number of semicyclic Latin squares of order N with fixed first row (excluding cyclic LS) (N<18) (was known before me)
