Presentation

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

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

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