Presentation

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

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

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