In the first part of this research we find an improvement to Huxley and Konyagin's current lower bound for the number of circles passing through five integer points. The improved lower bound is the conjectured asymptotic formula for the number of circles passing through five integer points. We generalise the result to circles passing through more than five integer points, giving the main theorem. In the second part of the research we consider questions linked to the distribution of different configurations of integer points of the circle passing through the unit square. We show that different configurations of points are distributed uniformly throughout the unit square for circles of fixed radius. Results are obtained by looking at the distribution of the crossing points of circles, where the circles form the boundaries of domains. The domain of a configuration is the set of possible positions of the centre of the circle within the configuration. We choose a rectangle within the unit square and then count the number of regions of the rectangle which are formed by domain boundaries.
