Presentation

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

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

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