Presentation

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

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

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