 OFFSET 0,2 COMMENTS Number of 3 X n binary matrices avoiding simultaneously the right angled numbered polyomino patterns (ranpp) (00;1), (01,1) and (11;0). An occurrence of a ranpp (xy;z) in a matrix A=(a(i,j)) is a triple (a(i1,j1), a(i1,j2), a(i2,j1)) where i11 and n>1. - Sergey Kitaev (kitaev(AT)ms.uky.edu), Nov 12 2004 If Y is a 5-subset of an n-set X then, for n>=5, a(n-4) is the number of 3-subsets of X having at least two elements in common with Y. - Milan Janjic, Dec 08 2007 Complement of A067251; A168184(a(n)) = 0. [Reinhard Zumkeller, Nov 30 2009] Where record values occur for the number of partitions of n into powers of 10: A179052(n) = A179051(a(n)).
