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