Ian sighed at the mention of anything being classified but focused on the work. Ian took off his sunglasses, finally, to look at the photographs.

What's the cube?

Ian took up two of the pages, comparing them and then setting them back down.

Seven groups. He was talking to himself more than Daniel. Finally he looked at the other man pointing out a group of symbols.

These three seem to be repeated in similar locations. These three too.

Ian looked puzzled. If this was a decoration the pattern would be regular.

Malcolm pointed back at the photograph. The pattern isn't uniformly distributed..uh.. like someone decorating a wall.

Ian went back to looking at the symbols and talking to himself again. Why would everything be in threes except the number of groups?
