Presentation

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

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

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