%N A120064 Shortest side b of all integer-sided triangles with sides a<=b<=c and 
               inradius n.
%C A120064 Terms a(11),..., a(100) computed by Thomas Mautsch (mautsch(AT)ethz.ch).
%H A120064 David W. Wilson, <a href="b120064.txt">Table of n, a(n) for n = 1..10000</
               a>
%e A120064 a(1)=2 because the only triangle with integer sides a<=b<c and inradius 
               1 is {3,4,5}; its middle side is 4.
%e A120064 a(2)=8: The triangles with inradius 2 are {5,12,13}, {6,8,10}, {6,25,
               29}, {7,15,20}, {9,10,17}. The minimum of their middle sides is min(12,
               8,25,15,10)=8.

               with integer inradius], A057721 [maximum of longest sides], A120063 
               [minimum of longest sides], A058331 [maximum of shortest sides],

               inradius n.
