# The variation of seven

Below is a picture of the IE team. Not all of them, just those based at the India Develoment Center (IDC).

Apart from their lovely smiles, I noticed something completely trivial about this picture - the number of different ways each has chosen to symbolize the number 'seven'.

They all mean the precisely same thing, but the variation amongst the team members on how they communicate the number is quite varied. Of the 13 team members in total:

• 5 hold the 'two' digits in their right hand
• 8 hold the 'five' digits in their left hand
• on the hand when two digits are displayed:
• 10 use the index and middle fingers
• of the other two people (we can see) one uses their little finger and the other uses his thumb
• all use sequential digits
• 11 are pointing all digits upwards, 2 are pointing them towards the photographer
• 12 have bent their arms
• 1 showed eight digits (!) - (thanks to eagle-eyed Peter for pointing out)

At this point, you might very well think I've lost my mind. You could well be right. But I find these little things quite fascinating.
