# User:Yosu Yurramendi/BinaryRectangularGrids

Number of binary pattern classes in the (m,n)-rectangular grid
with k   '1's and (m·n-k)   '0's

Two binary patterns are in same class if one of them can be obtained by a reflection or 180-degree rotation.

• A034851 : ( 1,n,k) triangle is the Losanitsch's triangle.
• A226048 : ( 2,n,k) triangle.
• A226290 : ( 3,n,k) triangle.
• A225812 : ( 4,n,k) triangle (with María Merino).
