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