Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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