Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 28 points:

(2,3)(5,6,9,10,8,11,7,12)(13,14)(15,22)(16,20)(17,19)(18,23)(21,25)(24,28)(26,27);(1,2,4,3)(5,7,8,9)(6,10,11,12)(13,15,16,23)(14,18,20,22)(17,26,25,24)(19,28,21,27);(1,3,4,2)(6,11)(7,9)(14,19)(17,25)(18,27)(20,21)(22,28)(24,26)
