Hi Hans,

many thanks for working on this and discovering the third term in the
'first n-tuply lonely non-twin' sequence.

Assuming your search would have brought up higher-than-triplies too, I'm
also grateful for your discovering that any fourth or higher terms (if
they exist!) must be greater than 2*10^9

Best regards,

Neil Fernandez
