Abstract: ABSTRACT A Heffter space is a resolvable configuration whose points form a half‐set of an abelian group and whose blocks are all zero‐sum in . It was recently proved that there are infinitely many orders for which, given any pair with odd, a 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 even.
