Presentation

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

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

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