[seqfan] Re: UnitaryPhi

[Richard J. Mathar]

In response to http://list.seqfan.eu/pipermail/seqfan/2018-August/018717.html:

I get the same values for a(2)--a(11), a finite value for a(12),
the same value for a(13) and a(16)-a(19),
but smaller values for a(14), a(15):

12 64281600 [1, [[2, 10], [3, 4], [5, 2], [31, 1]]]
13 13 [1, [[13, 1]]]
14 84672 [1, [[2, 6], [3, 3], [7, 2]]]
15 129600 [1, [[2, 6], [3, 4], [5, 2]]]
16 16 [1, [[2, 4]]]
17 17 [1, [[17, 1]]]
18 518400 [1, [[2, 8], [3, 4], [5, 2]]]
19 19 [1, [[19, 1]]]
20 ??
21 254016 [1, [[2, 6], [3, 4], [7, 2]]]

To clarify: (n-1)/n*m means (n-1)*m/n and UnitaryPhi = A047994.
