β¦ Synopsis
Transformation techniques due to Federico and Willcocks are applied to obtain the first known simple perfect squared square of order 24 from Duijvestijn's computer results for lower order. Similarly, twelve new simple squared squares of order 2.5 are added to the existing eight found by Federico and Wilson. Our emphasis is on four simple perfect squared squares of order 25 and common reduced side 540. They have 12 elements in common but have pairwise identical elements differently arranged.

## Abstract CΓ’mara A. and Wang Y.βH. (2010) introduce a simple square root option pricing model where the square root of the stock price is governed by a normal distribution. They show that their threeβparameter option pricing model can outperform the BlackβScholes option pricing model. We demonstr
