Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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