But the SPL reiterated that their fixtures were worked out on the basis of a pre-determined list of priorities and on the advice of a working group drawn from several clubs.
An SPL spokesman said: "According to reports in the press, Rangers FC will write to the SPL regarding the post-split fixtures.
"Any SPL club is welcome to seek an explanation from the SPL about its fixture schedule.
"This has happened in the past and may again in the future. We will respond to Rangers' letter once received.
"Included in some reports is a suggestion that the fixtures have been prepared to disadvantage Rangers FC and other clubs.
"This is both objectionable and entirely ludicrous.
"As we have already pointed out, the post-split fixtures are prepared on the basis of priorities.
"These priorities are designed to ensure the best possible balance of fixtures across all 12 clubs and are pre-determined by the SPL board, advised by the SPL fixture working group."
