Presentation

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

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

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