This is my favourite galaxy cluster, I love all the interacting and peculiar galaxies. It is actually the galaxy cluster containing the most number of Arp peculiar galaxies with four in total. They are:
1. Arp 71: NGC 6045, the elongated galaxy at the centre.
2. Arp 122, NGC 6040A and NGC 6040B, the weird and wonderful interacting pair of spirals near the top left corner.
3. Arp 172, IC 1178 and IC 1181, the two dancing galaxies near the top right corner.
4. Arp 272: NGC 6050 and IC 1179, the interacting pair to the right of NGC 6045.
Another one that should have been included is IC 1182, the severely distorted galaxy near the bottom right corner. What looks like a jet is actually a tidal tail, read more here:

wider view shows even more peculiar galaxies!
