Spread and partial spread constructions are the most powerful bent function constructions. A large variety of functions from a 2m-dimensional vector space $${\mathbb {V}}_{2m}^{(p)}$$ over {F}}_p$$ into can be generated, which constant on sets partition obtained with subspaces (partial) spread. Moreover, spreads one obtains not only between elementary abelian groups, but to B, where B any group...
