Heron triangles (n,b,c), Perimeter = 4*n and a pandigital number

 
 
The perimeter   =   4 \, n   and is a pandigital number, and a square number.

 

          Heron triangles   (n, \; b, \; c)
                  n \; = \; 34963569
Perimeter \; = \; 4\times 34963569 \; = \; 139854276 \; = \; 11826^2

215384976 = 4\times 53846244   ……   215384976 = 14676^2
326597184 = 4\times 81649296   ……   326597184 = 18072^2
412739856 = 4\times 103184964   …..   412739856 = 20316^2
537219684 = 4\times 134304921   …..   537219684 = 23178^2

HERON PAND 2

589324176 = 4\times 147331044   …..   589324176 = 24276^2
653927184 = 4\times 163481796   …..   653927184 = 25572^2
842973156 = 4\times 210743289   …..   842973156 = 29034^2
