I wonder if in the original list, a '1' was misread as a '7' or vice
versa. I am told that in some countries the '7' is conventionally
written with a crossbar across the downstroke to avoid this. My father
always did this, for all it is not common in England.
50 years ago, I worked for a British physicist who was studying the Van
Allen belts at Goddard Space Flight Center.
He crossed his '7's. But, he thought it odd when I slashed zeroes.
