Presentation

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

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

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