Abstract
This note describes a new technique for generating tight frames that have a high degree of symmetry and entrywise Gramian structure. The technique is based on a "lifting" construction through which, from non-maximal real equiangular tight frames of N vectors in r-dimensional space, we produce real unit-norm tight frames of
