Brahmagupta ( 628 CE ) started the systematic study of indefinite quadratic equations — in particular, the misnamed Pell equation, in which Archimedes may have first been interested, and which did not start to be solved in the West until the time of Fermat and Euler.

Euler was aware of the work of Lord Brouncker, the first European mathematician to find a general solution of the equation, but apparently confused Brouncker with Pell.

The first general method for solving the Pell equation ( for all N ) was given by Bhaskara II in 1150, extending the methods of Brahmagupta.

The first few Pell primes are

In words: the first two numbers in the sequence are both 2, and each successive number is formed by adding twice the previous Pell-Lucas number to the Pell-Lucas number before that, or equivalently, by adding the next Pell number to the previous Pell number: thus, 82 is the companion to 29, and 82

As well as being used to approximate the square root of two, Pell numbers can be used to find square triangular numbers, to construct integer approximations to the right isosceles triangle, and to solve certain combinatorial enumeration problems .< ref > For instance, Sellers ( 2002 ) proves that the number of perfect matchings in the Cartesian product of a path graph and the graph K < sub > 4 </ sub >- e can be calculated as the product of a Pell number with the corresponding Fibonacci number .</ ref >

As Knuth ( 1994 ) describes, the fact that Pell numbers approximate allows them to be used for accurate rational approximations to a regular octagon with vertex coordinates and.

As Martin ( 1875 ) describes, the Pell numbers can be used to form Pythagorean triples in which a and b are one unit apart, corresponding to right triangles that are nearly isosceles.

The park was used for military encampments during World War One and Two, with Camp Pell being used by United States forces during the Second World War.
