Makes sense. Six possible one-directional (A loves B, B loves A, etc) relationships that can be either present or not, so 2^6 = 64. Each person has 3 graphs where they’re disconnected but the others are not (A loves B, B loves A, A and B love each other), and one where there are no connections at all. 64 − 3*3 − 1 = 54.
