A python library for BIBD-related (Balanced Incomplete Block Design) calculations.
####BIBD definition: Let V and B be sets and I ⊆ V x B. A triplet (V, B, I) is a t - (v, k, λ) design if the following holds:
- |V| = v.
- Every block b ∈ B is incident (in relation I) with exactly k vertices v ∈ V.
- Every t-subset T of V is incident with exactly λ blocks b ∈ B.
####About this library: This library provides routines for testing existence of BIBD-s with certain paramethers, as well as construction of some BIBD-s.
