Presentation

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

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

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