permanent of (0,1) matrices

[Meeussen Wouter (bkarnd)]

n by n (0,1)-matrices with n upto 4
can have any Permanent in the range 0 to n!/2.

but for 5 by 5,
where a gross generalisation 
would allow any permanent
from 0 to 60, 

some values play hard to get:
{27, 35, 37, 41, 43, 45, 47, 49,
 51, 52, 55, 56, 57, 58, 59}

should we call them 
pentabhorent or cinquefuge,
or neither and just get on with work?
