Presentation

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

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

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