L etT be a square triangular grid with n rows and columns of vertices and n an even number. A set of edges E ⊂ E(T ) completely determines perfect matchings on T if there are no two dif- ferent matchings on T coinciding on E. We establish the upper and the lower bound for the smallest value of |E|, i.e. we show that 5 4 n 2 − 21 2 n +
