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