请将以下文字总结为一句话：

## Hickson 31 is a compact group of four galaxies that are very close to each other. Their interaction is fierce and often results in the formation of various celestial phenomena such as starburst regions and tidal tails, which are indicators of the ongoing processes in these galaxies. These intense interactions most likely have significant impacts on the evolution of each galaxy, leading to changes in their structures, star formation rates, and overall compositions.
