Presentation

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

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

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