There are many infinite families of BLT-sets, all of which have had their stabilizers computed except for the Mondello BLT-sets of Penttila. Following an introduction to, and survey of BLT-sets and their related geometries, we compute the group stabilizing the Mondello BLT-sets.born digitaldoctoral dissertationsengCopyright and other restrictions may apply.
