Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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