Presentation

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

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

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