A beprisque number nnn is an integer which is either one more than a prime number and one less than a perfect square, or one more than a square and one less than a prime. The 5th such number is 10.
81 is the largest square of a whole number...

26 5*5 and 3*3*3
the number is 24.. 24 is one less than 25 which is 5 squared when doubled its 48, which is one less than 7 squared (49)
No. It's one less than a square number.

Every non-negative real number is a square (every number if in the complex field) so every real number greater than or equal to -1 is one less than a square. Even if you restrict yourself to perfect squares, of the form n2, then n2 - 1 = (n-1)*(n+1) is one less than a square. There are infinitely many such numbers.
If you square a number less than one, but greater than zero, the result will be smaller than the original number. For example, 0.92 = 0.81.
There is only one even prime number and that is 2 as all over even numbers can be divided by 2 and 2 is not square so there isn't a number less than 100 that is an even prime square number.
