A (v,k,k-1) near resolvable block design (NRBD) is r-rotational over a group G if it admits G as an automorphism group of order (v-1)/r fixing exactly one point and acting semiregularly on the others. We give direct and recursive constructions for rotational NRBDs with particular attention to 1-rotational ones.

Abstract
A (v,k,k-1) near resolvable block design (NRBD) is r-rotational over a group G if it admits G as an automorphism group of order (v-1)/r fixing exactly one point and acting semiregularly on the others. We give direct and recursive constructions for rotational NRBDs with particular attention to 1-rotational ones.File allegati a questo prodotto
