Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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