Function stable_homotopy 

pub fn stable_homotopy(modulus: usize, k: i32) -> usize

The stable homotopy of the Eilenberg–MacLane spectrum HA: π_k(HA) = colim_n π_{n+k}(K(A,n)). For HA it is concentrated in degree 0 (|A| at k = 0, trivial elsewhere) — exactly what makes HA represent ordinary cohomology Hⁿ(−; A). Read off the stable range (N = 4).
