At the outset, we observe that the problem title mentions Omikron, Rho and Sigma. Now, we know that Omikron, Rho, Sigma are respetively the 15th letter, the 17th letter and the 18th letter of the Greek Alphabet.

Pi is the 16th letter of the Greek Alphabet, whose position is between Omikron and Rho, and we observe that Pi is not mentioned in the problem title.

Now, we know that the decimal expansion of the trancedental number Pi correct to 22 places is

as follows:

3.14159265358979323846264

Now, replacing each number by the letters located immediately below it on a keyboard, we obtain:

E.QRQTOWYTETIOUOEWE__IRYWY__

This corresponds to the given sequence (without the decimal point) and consequently the required next 5 letters are : I R Y W Y.
