COMMENT
|
In general the largest-bending ladder L across perpendicular corner where corridors of widths M and N meet,is given by L^(2/3)=M^(2/3)+ N^(2/3).
|
|
FORMULA
|
a(n)=d^3, where d=A006339(n).
|
|
EXAMPLE
|
a(4)=274625 because this is the smallest largest-integral-bending-ladder in 4 distinct stances, viz. with corridor width pairs (4096, 250047), (15625, 216000), (35937, 175616), (59319, 140608).
