We present a model of leptonic mixing based on two $A_5$ modular symmetries using the Weinberg operator. The are broken to respective diagonal subgroup. At effective level, behaves as with single flavour symmetry, but moduli. Using both stabilisers, different residual preserved, leading golden ratio that is perturbed by rotation.

We present a randomized approximation algorithm for counting contingency tables, m × n non-negative integer matrices with given row sums R = (r1, . . . , rm) and column sums C = (c1, . . . , cn). We define smooth margins (R,C) in terms of the typical table and prove that for such margins the algorithm has quasi-polynomial NO(lnN) complexity, where N = r1 + · · · + rm = c1 + · · · + cn.
