A ( v , k ; r ) Heffter space is a resolvable ( v r , b k ) configuration whose points form a half‐set of an abelian group G and whose blocks are all zero‐sum in G . It was recently proved that there are infinitely many orders v for which, given any pair ( k , r ) with k ≥ 3 odd, a ( v , k ; r ) Heffter space exists. This was obtained by imposing a point‐regular automorphism group. Here, we relax this request by asking for a point‐semiregular automorphism group. In this way, the above result is extended also to the case k even.
