Where to find the reference sequence used for phiX alignment?

The reference sequence used for PhiX alignment can be found in the Illumina iGenomes page.

All Illumina sequencing instruments already have the phiX reference, so the above reference is not required for assessing phiX alignment rates in sequencing runs. The sequence is made available as a reference, if needed.
