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