The squares of prime numbers greater than 10.
The sum of the squares of the first 100 natural numbers [1..100] is 338350, while the sum of the first 100 natural numbers squared is 25502500.
You can check which number from 1 to a 100 are squares of other numbers for yourself. Here's how: Start with 1 and count up, squaring the number and recording the result. Example: 12 = 1 22 = 4 32 = 9 . . . 102 = 100 The number 1, 3, 9 . . . 10 are squares Now, fill in the rest

Count the number of squares across the top of the grid, the count the number of squares down the side of the grid. Then multiply these two numbers If you have a grid of 100 squares by 60 squares then the number of squares in the grid is 100x60 = 6000
There are two prime numbers with squares between 100 and 300. These prime numbers are 11 and 13. (112 = 121 and 132 = 169.)

Infinitely many. There are a 100 perfect squares.
Prime squares: 4, 9, 25 and 49.
Numbers having exactly three factors are the squares of prime numbers. Examples of these numbers greater than 100 are 121, 169, 289, 361, 529, 841, etc.
I have noticed that they are all perfect squares.
Perfect squares have odd numbers of factors. The perfect squares less than 100 are: 1,4,9,16,25,36,49,64,81,100. 64 seems to fit both criteria.
